tracerCount is missing in several calls to EV_HLDM_FireBullets.

[malortie]

The two lines below do not pass &tracerCount[idx - 1] when calling EV_HLDM_FireBullets.

halflife/cl_dll/ev_hldm.cpp

Line 491 in c7240b9

EV_HLDM_FireBullets( idx, forward, right, up, 1, vecSrc, vecAiming, 8192, BULLET_PLAYER_9MM, 0, 0, args->fparam1, args->fparam2 );

halflife/cl_dll/ev_hldm.cpp

Line 796 in c7240b9

EV_HLDM_FireBullets( idx, forward, right, up, 1, vecSrc, vecAiming, 8192, BULLET_PLAYER_357, 0, 0, args->fparam1, args->fparam2 );

The code can crash with a null pointer exception if iTracerFreq different from 0 and tracerCount is unspecified.

halflife/cl_dll/ev_hldm.cpp

Line 312 in c7240b9

if ( iTracerFreq != 0 && ( (*tracerCount)++ % iTracerFreq) == 0 )

&tracerCount[idx - 1] should always be passed so that it points to a valid memory location.
